Error between trunk SIP - PJSIP

Hello, I’m migrating from SIP to PJSIP and now I’m configuring my trunks following and tutorials .

So I created a SIP peer on a Asterisk 13.11.2 server ( and configured the trunk into one PJSIP Asterisk 13.11.2 server (

My PJSIP Wizard for this register follows:

endpoint/allow = !all,g729

This is what the SIP peer looks like:

PabxIP-Teste*CLI> sip show peer 7799

The Dialplan context I’m using for the trunk (in my PJSIP server) follows:


exten => _XXXX,1,NoOp(TRUNK)
same => n,Set(CALLERID(num)=12345)
same => n,Dial(PJSIP/${EXTEN}@7799,75,T)
same => n,Hangup()

I can make a single call, I can see the flow in both asterisk’s consoles and there is no aparent error or warning relevant (can provide if necessary), but a moment after that first call the peer loses it’s register in server,

PabxIP-Teste*CLI> sip show peer 7799
Peer 7799 not found.

One thing I noticed is if I try to “qualify” the SIP peer before making the call, I can see the following NOTICE in my PJSIP server:

[Dez 28 09:50:40] NOTICE[1871]: res_pjsip/pjsip_distributor.c:525 log_failed_request: Request ‘OPTIONS’ from ‘“asterisk” sip:asterisk@’ failed for ‘’ (callid: 0e994d3117173c78534006357e4b32a8@ - No matching endpoint found

So my problem is that I can make only a single call per trunk and have to restart my Asterisk to it get register again and make another call, wich is not too good. Any lights?
Thanks in advance.

We are also trying to connect to a SIP Trunk through a PJSIP Server, and we stumbled upon the same issue. Have you found something yet?

You’ll need to provide more information. For example how is chan_sip configured? (File or database)? As the problem appears to be on that side, and not on the chan_pjsip side. You will also need to provide all the console output on both sides.

Hello, @jcolp, I figured out the problem was on using pjsip_wizard.conf instead of pjsip.conf since it was needed to use realtime. The solution was simple: return to pjsip.conf.
